On top of the general pitch for your track, you can also write personalized messages to each contact that you've chosen within your campaign, in the section located just underneath the one dedicated to the general pitch.
When and how to write a good "personalized message"?
First of all, it's important to note that personalized messages are not mandatory. If your time is limited and the general pitch of your track is already well detailed, you don't need to feel obligated to write a personalized message to each contact 😊 You can also prioritize writing personalized messages to the contacts in which you're the most interested.
However, if you've got the time, these messages can be a real asset, especially when you get in touch with curators, record labels and pros for different reasons within the same campaign. In a personalized message, you can notably detail what you're looking for when getting in touch with this particular contact, but also evoke a previous encounter/email exchange or a personal element that you like with them (for instance: an article of them that you've read, their artistic line if it's a media outlet, an artist of their roster if it's a record label)
💡 Tip: don't hesitate to address the curator / pro by their name or the name of their entity - without spelling mistakes - and why not in an enthusiastic or surprising way! It's the kind of small attentions which can help you distinguish yourself from other artists 😉
